My research interests are in distributed systems, storage systems, operating systems, system security, and wireless communications, with an emphasis on bridging theoretical foundations and practical systems. I am serving on the editorial board of ACM Transactions on Storage and served on the program committees for NSDI 2015, Eurosys 2014, SOSP 2013/2011, OSDI 2012/2010, DISC 2009, and PODC 2006. I was the PC co-chair for the 7th Workshop on Large-Scale Distributed Systems and Middleware (LADIS), 2013; the 1st ACM SIGCOMM Asia-Pacific Workshop on Systems, ApSys 2010, New Delhi, India, August, 2010.
